Can anyone help me with the two questions below? I don't exactly understand it. For b) I tried Taylor series.



a) find all critical values if you can by partial s at 2nd degree



b) replace $e^x$ and $ln(1+y)$ by enough terms to include all quadratic terms

    what does "partial s at 2nd degree" mean? Also, please improve the mathematical notation by using MathJax.
